Many conventional digital library systems offer access to their collections only via full text or meta-data search, or by browsing-access via a hierarchy of categories. With the increasing amount of digital content available, alternative methods to access the content seem necessary. The SOMLib system, which is based on using Self-Organizing Maps (SOMs), has been used to automatically organize documents of a digital library by their content. In this paper, we present an integration of this system into the popular open-source digital library system Greenstone, combining searching and explorative browsing through the thematically organized content using the map. We present the system on a demo collection consisting of the abstracts of papers and posters from the last 5 years from the JCDL, ECDL and ICADL conferences.
